In , K. Kishimoto introduced the notion of P-Galois extensions and gave some fundamental properties of these extensions. P-Galois extensions relate Hopf Galois extensions, and the author treated these topics in . Moreover, the cubic P-Galois extensions over a field were completely determined in . Continuing  and , we classify commutative quartic P-Galois extensions over a field of characteristic not 2.
